Atomics International, Canoga Park, Calif. THERMAL PROPERTIES OF REFRACTORY MATERIALS, by J. A. Cape and R. E. Taylor.

The thermal conductivity of TiC was measured over the temperature region 400 to 1200 deg C by the steady state radial heat flow method. The conductivity varies linearly from 0.088 calsec cm degree C at 500 deg deg C to 0. 109 calsec cm degree C at 1100 deg C. These results are in marked contrast to values reported in the literature. The techniques and apparatus for measuring the specific heat of brittle conductors by pulse heating are described. Resistivity and specific heat data for uranium silicide of several compositions are reported. The resistivity and specific heat increased with increasing silicon content. For uranium silicide containing 3.8 silicon, the resistivity increased from 56 microhm-cm at 0 deg C to 75 microhm-cm at 750 deg C and for uranium silicide containing 5.9 silicon, the resistivity increased from 81 microhm-cm at 0 deg C to 111 microhm-cm at 800 deg C.
